[dpdk-dev] [PATCH 5/5] net/mlx5: add vectorized Rx/Tx burst for SSE4.1

Yongseok Koh yskoh at mellanox.com
Thu Jun 29 01:04:03 CEST 2017


To make vectorized burst routines enabled, it is required to run on x86_64
architecture which can support at least SSE4.1. If all the conditions are
met, the vectorized burst functions are enabled automatically. The decision
is made individually on RX and TX. There's no PMD option to make a
selection.
